Okay, okay so humor me on this. What is there to have fun with in this game? All the sidequests are the same, there’s no progression, there’s no real dungeons to raid or say massive NPC ships to attack and loot. The only “fun” you get is watching just how stupid the enemy AI is or griefing some random twats for about ten minutes, before you realize “Oh wait, there’s no real punishment for doing this, neither to them or me”

The Gamecube version was good since it was all on the one disc unlike the Dreamcast version which required two and the load times were faster. It also had more story content and side quests to do, namely the Bounties where you had to hunt down other pirates.
But that came at the cost of sound compression. Sounds would often desync from the animations and the music is notably worse in quality. Some songs didn’t even loop properly, most noticeably the Gigas theme.

Yeah. Plus the GC had a bunch of extra stuff like the bounty missions. And the one girl that kept chasing you. All that made your level extra high. The new battles was balanced to match the new leves. The old bosses where not. So at the time you got to the last part of the game, having done all the new extra fights. Your level was why higher then what you normally would have after a playtrough(unless you spend hours grinding), this made the last boss fights in the GC version a walk in the park.
